GaS (alpha phase Gallium sulfide)
GaS (alpha phase) is a semiconductor with an indirect band gap of ~2.6 eV. The layers are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers. α-GaS belongs to the group-13 post-transition metal monochalcogenides.
The Gallium sulfide crystals produced at HQ Graphene have a typical lateral size of ~0.6-0.8 cm. The crystals are yellow colored and transparent.
